Helium Bomb

When an asteroid nearly 600 times greater mass than the one that killed the great dinosaurs and all surface life is about to smash into the Earth, it will bring global devastation. All life will end right down to the smallest single-celled creatures in the depths of the oceans, leaving the Earth a lifeless hulk. How can an asteroid fifty miles across be diverted from its deadly course?There is no way to evacuate over six billion people to another planet in time or to feed and clothe them if there were. As Professor Grymm says, "e;Even magic has limits."e;The largest thermonuclear bomb available would not be powerful enough to knock a fifty mile diameter hunk of space rock into a safe orbit. However, back on Abras a rumor is heard that a certain scientist has designed a super bomb that could possibly solve Earth's problem. Regrettably, that scientist along with the bomb plans have disappeared without a trace.To further confound things, when the main characters fly to the asteroid to look around, things get a bit crazy as they discover things are not exactly as they appear.[ No blatant sex or adult language; a few innuendos suggest that readers be a bit mature, or parents could read the story first, to decide if it is right for their teenagers.]
